The lit LED position marks the hour, and its color represents the minutes. During the course of an hour, each LED changes colors in 20-minute intervals, going from red to green to blue to red, and, thus, demonstrating the full-range of possible color combinations.
TLC5940 arduino. [SOLUCIONADO] Multiplexando tiras de leds RGB. Lo del problema con el BC558 es el siguiente, mis cálculos me daban que dejando la salida en 0 el TR no se debería excitar, y piniendoló en 1 (5v) se excitaría y el BC558 me habilitaría los 12v a la tira. Actualmente dejandoló al aire está apagado, poniendoló a 0v se activa y a 12v se apaga.
Y lo raro es que con 5v o tocandoló con la mano, queda a medio encender. Como que los 0v de la salida PDx no llega a cerrar el circuito.

Simulando el circuito con resistencias todas ellas de 1kohm en teoría funciona. imagino que GND de la alimentación de 5 voltios y la de 12 vltios la tienes unidas, si no no hay tu tia.. un saludo.

RGB LED :: mbeckler.org. Abstract: I picked up a cheap RGB LED from RadioShack (276-028) on my way home from school/work yesterday. I recently built an Arduino so I thought that using this RGB LED with PWM output would be a fun way to get introduced to the Arduino way. Using three external potentiometers, I was able to mix different proportions of red, green, and blue in the same LED, producing nearly any color imaginable. General Description: The Arduino is a pretty slick platform for microcontroller development based on the Atmel line of microcontrollers. The system comes with some convenient functions for initialization and operation, that really help decrease the development time for most projects. For this little project, I want to connect a tri-color RGB LED to the microcontroller with PWM ("analog") outputs to control the brightness of each color, and use three analog inputs to set each color's brightness.
Circuit Schematics: The circuit is divided into two sections, the Input and Output sections. Résultats de recherche pour : 'arduino' Ou acheter ce composant électronique : fournisseurs. Accueil RER-ELECTRONIC.FR. Tutoriel sur le contrôle de leds RGB.
